Systems, apparatuses, and methods for removal of orbital debris are provided. In one embodiment, an apparatus includes a spacecraft control unit configured to guide and navigate the apparatus to a target. The apparatus also includes a dynamic object characterization unit configured to characterize movement, and a capture feature, of the target. The apparatus further includes a capture and release unit configured to capture a target and deorbit or release the target. The collection of these apparatuses is then employed as multiple, independent and individually operated vehicles launched from a single launch vehicle for the purpose of disposing of multiple debris objects.

1. An apparatus for debris remediation, comprising: a spacecraft control unit comprising at least one processor configured to guide and navigate the apparatus to a target;a dynamic object characterization unit configured to match a rate of the apparatus with a rate of the target to characterize move
1. An apparatus for debris remediation, comprising: a spacecraft control unit comprising at least one processor configured to guide and navigate the apparatus to a target;a dynamic object characterization unit configured to match a rate of the apparatus with a rate of the target to characterize movement of the target for debris remediation; anda capture and release unit configured to enter through an engine nozzle of the target to remove the target from a congested orbit to an uncongested orbit or to Earth for disposal without creating additional debris. 2. The apparatus of claim 1, wherein the capture and release unit comprises: a mast, a plurality of throat sensors, and a plurality of tip sensors. 3. The apparatus of claim 2, wherein the mast is configured to extend into the engine nozzle of the target. 4. The apparatus of claim 2, wherein the mast is further configured to retract after capturing the target. 5. The apparatus of claim 2, wherein the mast comprises a snare configured to inflate within the engine nozzle of the target to facilitate capture of the target. 6. The apparatus of claim 2, wherein the mast comprises a plurality of rollers configured to guide the mast within the engine nozzle of the target. 7. The apparatus of claim 2, wherein the plurality of throat sensors are configured to detect whether the mast has entered the engine nozzle of the target. 8. The apparatus of claim 2, wherein the plurality of tip sensors are configured to detect whether the mast is in physical contact with the engine nozzle of the target. 9. The apparatus of claim 1, wherein the capture and release unit further comprises a plurality of airbags configured to inflate within the engine nozzle of the target to align the apparatus with the target. 10. The apparatus of claim 1, further comprising a cowcatcher configured to protect the capture and release unit and react launch loads of the apparatus. 11. The apparatus of claim 1, further comprising a plurality of rollers configured to guide the apparatus within the engine nozzle of the target. 12. The apparatus of claim 1, further comprising: a plurality of pressurized helium tanks containing pressurized helium. 13. The apparatus of claim 12, wherein at least one of the plurality of pressurized helium tanks is configured to release the pressurized helium into a mast to cause the mast to extend into the engine nozzle of the target. 14. The apparatus of claim 1, further comprising: a power unit configured to power the apparatus prior to, during, and after, capture of the target. 15. The apparatus of claim 14, wherein the power unit comprises a solar array configured to provide energy to the apparatus. 16. The apparatus of claim 15, wherein the solar array is further configured to expand when collecting energy. 17. The apparatus of claim 15, wherein the solar array is further configured to retract when the apparatus performs a rendezvous and capture sequence on the target. 18. The apparatus of claim 14, wherein the power unit further comprises at least one battery configured to provide energy to the apparatus. 19. The apparatus of claim 1, further comprising: a propulsion unit configured to drive and rotate the apparatus. 20. The apparatus of claim 19, wherein the propulsion unit comprises a main engine configured to drive the apparatus in a forward direction. 21. The apparatus of claim 19, wherein the propulsion unit further comprises a plurality of thrusters to rotate the apparatus. 22. The apparatus of claim 1, wherein the spacecraft control unit is further configured to perform an autonomous approach to a target and control the target when the target is captured. 23. The apparatus of claim 1, wherein the dynamic object characterization unit is further configured to analyze physical and motion characteristics of the target to enable the spacecraft control unit to produce an approach and capture solution. 24. The apparatus of claim 23, wherein the physical and motion characteristics of the target are analyzed based on data received from a plurality of sensors. 25. The apparatus of claim 1, further comprising: a plurality of noise radars configured to provide data with respect to a motion of the target. 26. The apparatus of claim 1, further comprising: an infrared camera configured to provide bearing data when rendezvousing with the target. 27. The apparatus of claim 1, further comprising: an infrared camera configured to capture media of a target, and provide the media to a ground control unit when rendezvousing with the target, whereinthe media comprises video data, image data, or both. 28. A method for debris remediation, comprising: performing, by an apparatus comprising at least one processor, a rendezvous procedure with a target;analyzing, by the apparatus comprising the at least one processor, the target prior to capturing the target;capturing, by the apparatus, the target through an engine nozzle of the target after a rotation rate of the apparatus is matched with a rotation rate of the target; andremoving, by the apparatus, the captured target from a congested orbit to an uncongested orbit or to Earth for disposal without creating additional debris. 29. The method of claim 28, further comprising: separating from a launch vehicle at lower earth orbit. 30. The method of claim 28, further comprising: loitering in lower earth orbit until the target is near the apparatus. 31. The method of claim 28, wherein the rendezvous procedure is performed when orbital planes of the target and apparatus match. 32. The method of claim 28, further comprising: calculating an approach to the target based on the analysis of the target. 33. The method of claim 28, wherein the capturing of the target comprises performing a translation and rotation thrust to place the apparatus in proper orientation on a radial pattern with an X-axis of the apparatus positioned near the engine nozzle of the target. 34. The method of claim 28, wherein the capturing of the target comprises adjusting and stabilizing the apparatus to position the apparatus in a proper relative position and attitude on a radial pattern with an X-axis position on a centerline of the engine nozzle. 35. The method of claim 28, wherein the capturing of the target comprises matching a plane of the apparatus with a plane of the target. 36.
